Toallwhom it may concern:

Be -it lmown that I, GEoncE J. ZlscH, a subject of Germany, and aresident of Newark, in thevcounty of Essex and State of New, Jersey,have invented certain new and useful Improvements in Carbureters, ofwhich the following is a specification.

The/invention relates to improvements in carbureters for hydrocarbonengines, and it consists in the novel features, arrangement andcombinations of parts hereinafter described, and particularly pointedout in the claims. n n

The object of my invention is to provide a simple and highly elicientcarbureter for automatically supplying gas of the requisite quantity andqpality to the cylinder of an engine, 1n accordance with the work to be'performed. I contemplate the use of my carbureter in connection with thecylinders of automobile engines for supplying gas thereto.

The lcarbureter of my invention' comprises, preferably, a cylindricalcasing affording a mixing chamber for the air and gas to be connected bysuitable piping with the en gine cylinder, and a receptacle for thegasoing-chamber and to be connected with a suitable tank or source ofsupply for the j gasolene.

The receptacle -containing the gasolene will be provided with afloat forclosing,

in accordance with requirements, and saidtube or pipe leading from saidvalve mechanism into said mixing-chamber and preferably Aformin thepivotal axis 'of a suitable valve ofvthe utterly type for controllingthe passage through said chamber. said tube or pipe is formed, withinthe'mxing-chamber, with an outlet opening for n gasolene and preferablycontainsa wick or body of absorbent substance which becomes saturatedwith the gasolene and while permitting a proper discharge thereof intothe mixing chamber prevents any undue quanto said chamber above thebutte through the carbureter.

asolene from the tank or The i.

tity 'of theA gasolene from entering said chamber; The mixing chamber isprovided Patented lie. 5, 1911.

at its lower portion with a suitable air inlet and anv automaticcheck-valve therefor. The butterfly valve controlling the passagethrough the mixing chamber and the valve mechanism controlling 'thevariable passage of gasolene to the discharge tube or pipe connectedwith said valve and adapted to discharge into said chamber are.connected together and operate synchronously tov admit properproportions of air andgasolene y' valve in accordancel with the workrequired, whereby as the buttery or air valve is turned to increase theopening through the mixing chamber, the said valve mechanism willlikewise open to a greater extent tofsupthe increased quantity of'airthen passing My invention results in proper combus tion, high eiciencyin the engine and great economy in the consumption of the gasolene, aswell as accomplishing other important advantages.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to' 'the accompanyingdrawings, in which: Y

Figure 1 is a central 4.vertical section through a carburetery embodyingmy inven- 'ply the requisite quantity of gasolene to tion, the sectionbeing on the dotted lines 1--1 of Figs. 2 and 4; Fig. '2-isa like secftion of the same taken at a right angle to the section of Fig. 1 and onthe dotted lines 2-.-2 of Figs. 1 and 4; Fig. 3 is a horizontal sectionofthe same on the dotted line 3-3 of Fig. 2; Fig.- 4is a top view ofthesame,

the pipe leadingv from the carbureter to the engine cylinder being shownin horizontal section;Fig. 5 is an enlarged detached vertical section,on the dotted line `5 -5 of Fig. 2, of the gasolene valve mechanism forsecuring a variable admission of 'the gasolene tothe transversedischarge pipe or tube in the mixin chamber; Fig. 6 is a like sectionthrough t e same on the dotted line 6-6 of Fig. 2, Fig. 7 is an enlarged4detached view of the wick or absorbent body which I prefer to employinthe transverse gaso-v lene discharge pipe or tube, and Fig. 8 is asectional view correspondin but showing a modification o thegasolenevalve mechanism in that the valve-disk (3l) with Fig.` 5v l tures ('32)shown in Fig. 5.

In the drawings, 15 designates the exterior` cylindrical shell or casingof the carbureter, 16 a top plate thereon, 17 a bottom plate appliedthereto, 18 a vertical tubular section concentric with and within thesaid exterior casing and forming within it the mixing chamber andconduit for the air and gas, and 19 a semi-circular float within thegasolene-receptacle 20 formed between the exterior casing 15 and tubularsection 18, said float preferably being-in two members connectedtogether by a plate 14 hinged to a bracket 13 and having a laterallyprojecting lip or lever-arm l2, as shown more clearly in Figs. 2 and 3.

The receptacle 20 may be supplied with gasolene or the like from asuitable tank, not shown, connected with a nipple 22 screwed into thetop-plate 16 and having a port, 23 leading to said receptacle. At .theupper portion of the rt 23 is a valve-seat, as shown in Fig. 2, a aptedto the valve 24, whose stem 25 extends downwardly through the port 23 inposition to be acted on by the lever-arm 12 of the float 19 to open saidport when the float descends by the lowering of the level of asolene inthe receptacle 20 so that an additional supply of gasolene may entersaid receptacle. When the level of the asolene in the receptacle 20lowers, Vthe oat 19 will turn downwardly and cause the lip or lever-arm12 to move upwardly against the valve stem 25 and elevate the valve 24rom'its seat to admit an additional quantity of gasolene to thereceptacle 20, and then as the gasolene reaches its predetermined levelin the receptacle the float riding upwardly will turn the lip orlever-arm 12 downwardly from the valvestem 25 and permit the valve 24 tolower and close `the port 23, thereby cutting o the supply of asolene tosaid receptacle.

The out et for gasole'ne from the receptacle 2O to the mixin lchamber 18is through a valve-mechanismthe transverse pipe or tube 26 which ispivotally mounted and extends transversely across the mixing chamber andis provided with an outlet orifice 27 in said chamber, saidvalve-mechanism comprising a stationary disk 28 having an arcuate recess29 open at theouterface of the disk and in commnnication with a ort 30opening freely. through the edge 0F the disk into said receptacle,-anrintermediate disk 31 rigid on the adjacent end of the pipe or tube26 and having a series of ports 32 of preferably gradually increasingdiameter arranged on the arc of a circle and to be brought one afteranother into register with the arcuate recess 29, and an outer cap 33fitted upon and secured to a laterally projecting periph- Figs. 2, 5 and6) and eral iiange on the disk 3l and forming bel tween itself and saiddisk 31 a chamber 34 which is closed at its outer side by said cap andinto which chamber the end of the pipe or tube 26 o ens to receive itssupply of gasolene there rom. The chamber 34 receives its gasolenethrough the port l30 and recess 29 of the disk 28 and through such ofthe series of ports 32 of the rotary disk 31 as may at the time be inregister with the said recess 29, the flow of gasolene to said chamberand thence into the discharge pipe or tube 26 bein variable in quantityaccording to the positlon of the ports 32 of the disk 31 with relationto the recess 29 of the disk 28.

The disk 28 has a hub portion set into the side wall of the mixingchamber 18 and it is stationary and affords a bearing for one end of therotary pipe or tube 26. The disk 31 is fast on the end of the pipe ortube 26 and is in .face to face engagement with the disk 28, being heldfirmly in such engagement by means of a nut 35 on the open end of thepipe or tube 26 and a spring 3.6 on said pipe or tube and actingexpansively between a side wall of the mixing chamber 18 and a collar 37on the outer solid portion of the said pipe or tube. The spring 36 andcollar 37 are within a chamber 38 partitioned off from the receptacle 20, and said collar carries a stop-arm 39 provided to limit the rotarymovement of the pipe or tube 26, said arm at its lower end contactingwith the wall of the chamber y38 when the said -pipe or tube has turnedto the extent intended to be permitted and arresting the same.

The tube or pipe 26 carries, within the mixing chamber 18, aA disk orbutterfly valve 40 which is utilized to more or less open or close thepassage through said chamber, said valve, tube and the gasolenefeed-control disk 31 always moving in unison and hence proportioning therespective quantities of gasolene and air that shall vcome together inthe mixing chamber above said valve 40. The tube or pipe 26 and partsconnected with it receive their motion under the manual control of theoperator or driver through any suitable mechanism comprising, forillustration, a connecting rod or link 41 pivoted to a cranklarm 42rigid on a solid projecting end 43 of the tube 26, said end 43 and tube26 being mounted to have a rocking or angular movement to such extent asmay be required for admitting the proper quantities of air andgasoleneto the mixing chamber 18 and securing the proper mixture for theengine cylinder in accordance with the work to be performed.. The tube26 will preferablycontain a wick 50 or similar absorbent body adapted tohold a body ot the gasolene and aid in controlling the discharge fromsaid tube into the mixing chamber.

The upper or cap-plate 16 contains a cen- "iti chamber and said platemay be fastened by screws 44 to the usual engine cylinder. y

The bottoni-plate or capv 17 has air-inlets 46 of small size leadin toan interior airpipe 45 leading to the chamber 47 formed in t e lowerpart of the` casing 15, and also a 'large air-inletv or opening 47leading to said chamberbut normally kept closed by a check-valve 48 heldon its seat by 'a light spring 49. During t-he use of the 'carbureterthe valve 48 will be automatically opened to a greater or less extent asmay be required by the suction created by the piston of the engine onits suctionstrokes. In the chamber 47 is provided a disk 51 ofwire-cloth to screen the air which may pass to the mixing chamber. v

The top and bottom plates 16, 17 may be removably clamped against theends of the casing 15 by means of vrods52 whose upper ends are in theform `of adjustable bifurcated members straddling lugs 53 on thetop-plate and carrying eccentrics 54 to be operated by handles 55for'engaging, with binding force, the upper concaved surfaces. of saidlugs.

The lower ends of the rods 52 are confined in lugs 56 on the bottomplate 17 and are provided with heads 57' to prevent their upwardmovement through said lugs. By releasing the eccentrics 54 the casing 15and all its parts below the topplate 16 may be removed from thevehicle,V

and this is a feature of advantage for several reasons. l

The operation of the carbureter will be understood from the foregoingdescription withoutgfurther extendeddetailed description.

The carbureter having been applied to position and the receptacle 20having been supplied with gasolene, the operation of the airvalve 40 andgasolene disk-valve 31 for the admixture of the gasolene and air will beunder the direct control of the driver on the.

car through the medium of the connecting rod 41, crank-arm 42 and tube26. The suc' tion stroke of the piston of the engine will be dependedon, in the form of my invention illustrated, for opening the air-valve`48. The driver will open the valves 40, 31

to a4 greater or less extent as the requirelments of the enginemaydemand. f It is one of the important features of the invention that bymeans of the valve 31 the driver may regulate the quantity of gasolenethat shall escape to the mixing chamber and that at the same time he maycontrol, by the posit-ionfof thevalve 40, the quantity cf air in saidchamber to mix with the gasolene. The operation`- of the valve 40 incontrolling the passage of air through the mixing chamber is obvious.The disk-valve 31 contains the series of apertures 32 which in effectconstitute an elongated narrow port and as said disk is turned to carrymore or less of the port into communication with the gasof thence escapeinto the mixing chamber 18- will vary accordingly. If only a light loadis imposed on the engine onlyfa small quantity of gasolene will berequired; under a heavier load a larger quantity of the gasolene will berequired, and under a maximum load a still larger quantity of thegasolene will be required, and all these variable quantities ofgasolene, with the proper proportionatequantities of air, may be securedby the simultaneous movement of the diskvalve 31 and air valve 40. Whenthe diskvalve 31 is moved to carry say two of its apertures 32 intoregister with the recess 29 .a certain quantity of gasolene may pass te'the pipe 26, and as more of said apertures are carriedinto registerwithsaid recess a larger volume of gasolene is permitted to pass to thepipe 26. As the pipe -26 is turned By means of my invention the drivermay very readily regulate the escape of the gasolene into the mixingchamber and the passage of the `mixture ofgasolene and 'air through thecarbureter to the engine.

The series of apertures 32 in the disk 3l will preferably be ofgradually increasing diameter, as shown inv Fig. 5, although I do notregard this as a limiting feature of my invention. Il desire it tobe'understood that I do not limit my invention to the vforms and.details of construction hereinbefore specifically described, since thesemay vary considerably within the plan and spirit of my invention andwith individual preference or judgment. I illustrate the elongated portthrough the valve-'disk 3] as composed of a series of apertures 32 but Ido not confine my invention to the separate apertures since if thepartitions between the apertures were cut away, thus leaving a narrowslot, as

.air-valve40is transversely across the mix- `mg chamber, as shown,only-one of the apertures 32 in the disk 31 will be in communi.- cationwith the recess 29.
